Random generation tools - Character, NPC, Monster, Hireling, Encounter, and Faction
- Random or manual generation of Cairn 2e, Custom 2e and Barebones characters — each source toggles on or off, and Character Creation Mode re-rolls single parts until the person feels right
- Rolled one at the table instead? Clear Use random generation and the same button opens an empty sheet, with the pick-lists ready and nothing handed to you
- The Warden's Dashboard — every one of the 45 Warden roll tables on a button, in one resizable, detachable window: travel and weather, encounters by terrain, NPCs, factions, monsters, and any table you have made yourself. Rolls stay private to you unless you say otherwise, and the generators and Warden's Damage are on it too
- NPC, hireling, monster and faction generators — a career or a Background over a rolled stat block and a full pack, a complete monster from a danger tier, a faction dossier from the Setting Seeds tables — plus encounter tables with one-click Add to Scene

Other unique features
- .json character import from the official Cairn app, Kettlewright — for the Warden, and for players bringing in their own characters when the Warden allows
- Player-to-player item offers — give an item from its inventory row, or by dragging it onto another character's sheet; the offer is a chat card the other player accepts or declines, and accepting into a full pack simply over-burdens them after a warning that names the cost
- Pop-out and printable character sheets — the whole character on one or two pages!
- A fully customizable marketplace - add items or edit existing items
- Watches, and a Calendar — a day is three watches in Cairn, and the current one sits on everyone's screen above the player list. Vald's own calendar is there as an optional hack: twelve months, a six-day week, four seasons with a weather table each, a month grid anyone can open from the clock, a weather log, and room for the Warden's own days
- Works with the Torch module — a ready-made light-source file lights torches, lanterns, candles and the stranger lamps straight from the inventory, spending their uses
- Tooltips for players, and minimal automation — the rules stay in your hands
